Whether a self-funded vaccine should be administered depends on which vaccine it is, not whether it is self-funded or free. Whether a vaccine is included in the national immunization program, that is, as a free vaccine, the cost of vaccination has to be considered, in addition to the danger and prevalence of the disease for which the vaccine is intended. Some vaccines, such as the 7-valent pneumonia vaccine for children against pneumococcal diseases, are unlikely to be included in the national immunization program in the near future because they are expensive, while the application of vaccination abroad has sufficiently demonstrated its safety and efficacy that it has begun to update and promote the 13-valent pneumonia vaccine for children. In fact, it is because of the low rate of pneumonia vaccination among children in China at present, pneumococcal diseases are still prevalent in our country and are more harmful to children, especially the frail ones, so it is still worthwhile for parents with financial means to pay for their babies. In addition, Haemophilus b vaccine, rotavirus vaccine, and influenza vaccine are all self-paying vaccines that are worth considering. In addition, some newer vaccine forms, such as the five-dose vaccine that includes diphtheria, tetanus, pertussis, polio and Haemophilus influenzae type b, can greatly reduce the number of shots your baby receives, but are also self-paying vaccines. Is it better to have more vaccinations? There are more and more vaccines for different diseases, so it is not necessarily true that it is worthwhile to get them all and that more vaccinations are better. Since the prerequisite for babies to get infectious and contagious diseases is exposure to pathogenic microorganisms, if it is impossible for a baby to encounter a pathogenic microorganism, it is impossible to get the disease and there is no need to receive the corresponding vaccine. At the same time, the purpose of vaccination is to prevent disease, if the safety of the vaccine is not very reliable, then it is not necessary to vaccinate. For example, yellow fever vaccine, typhoid vaccine, paratyphoid vaccine, etc., these vaccines have to be administered only when entering an infected area, and the majority of children do not need to be vaccinated. Should I get the imported or domestic ones? Since the purpose of vaccination is to prevent disease, and since vaccination is equivalent to simulating a pathogenic microbial infection, the safety of the vaccine is quite important. A mother’s focus in choosing a vaccine for her baby is not on whether it is imported or domestic, but rather on its safety. So how do you consider whether a vaccine is safe? Since adverse reactions to vaccines are a small probability event, it is difficult for mothers to judge vaccines based on their own ability alone, and they have to rely on the government health department and other related departments to monitor the whole process of vaccine manufacturing, as well as the collection and analysis of adverse events, which means that the manufacturing, application and feedback of vaccines should be transparent in order for mothers to have information about the safety of vaccines. What is the difference between attenuated and inactivated, and which is more suitable for babies? Attenuated vaccines are vaccines that contain live pathogenic microorganisms, but these pathogenic microorganisms have been modified for a long time and hardly cause disease, and infection causing disease only occurs in extremely occasional cases. In contrast, inactivated vaccine means that the vaccine contains only dead pathogenic microorganisms, mostly some cellular components of pathogenic microorganisms or exotoxins, etc., which certainly cannot cause disease. In other words, inactivated vaccines are safer than attenuated vaccines. However, the immune effect of attenuated vaccines is higher than that of inactivated vaccines, and generally sufficient antibodies can be produced after one vaccination; whereas inactivated vaccines require several repeated vaccinations to produce sufficient antibodies. If I miss a vaccination, do I have to postpone the next vaccines? If you miss the vaccination time, the vaccination for the next vaccine will depend on the situation. For example, the routine vaccination for hepatitis B is at birth, 1 month, and 6 months. If the baby misses the first vaccination due to premature birth or some other reasons, then the first vaccination should be given as early as possible, and then the second vaccination should be given after an interval of 1 month. The third vaccination can be appropriately advanced, as long as the interval between the second vaccination and the second vaccination is more than 1 month, and there is no need to wait for 5 months before the third vaccination. If there is a delay in receiving polio vaccine and DPT3 vaccine, you can also start vaccination as early as possible after your baby is suitable for vaccination, and receive the vaccine at an interval of one month to complete the basic immunization three times in a row. A booster immunization will be given when the baby is 18 months old. What is the maximum number of shots that can be given at one time? At present, babies need more and more vaccines, and some babies have postponed vaccination for various reasons, so sometimes they have to have several shots at once, and it is difficult to say how many shots they can have at most. However, when my daughter and I first arrived in the U.S., we were given four shots at a time to catch up on vaccinations and did not feel any discomfort. Of course, more and more vaccines are now being made into combined vaccines, such as various triple vaccines and quintuple vaccines, so you can get multiple vaccinations with one shot, which can greatly reduce the number of shots your baby needs. In addition, since the human immune system needs a certain amount of time and a certain procedure to produce antibodies, each vaccination must be given at least 4 weeks apart in order to avoid mutual interference between vaccines. This means that vaccinations can only be given every 4 weeks, but multiple vaccines can be given at one time. Can a child with allergies be vaccinated? If a baby is allergic to a component of a vaccine and has had a serious adverse reaction to the vaccination, then of course he or she should not receive the same or similar vaccine again. However, what mothers are concerned about is whether some babies with allergies such as eczema or those diagnosed with milk protein allergy or egg allergy can be vaccinated. In fact, babies with eczema and milk protein allergy can be vaccinated perfectly well, and babies with egg allergy only need to be cautious when receiving some of the flu vaccines, which cannot be used for patients with severe egg allergy, while all other vaccines can be given. Of course, if your baby has significant allergy symptoms, it is recommended that you hold off on vaccination until the symptoms have subsided. Can I get vaccinated during a cold? No. Minor cold symptoms do not affect vaccination, but it is generally advisable to hold off vaccination during a cold and wait until your baby has recovered from the cold before vaccination. If you miss vaccinations during the cold, you can make up for them later. How can I still get sick after receiving vaccinations? Vaccination produces antibodies in the body, which can resist the invasion of the same pathogenic microorganisms and protect the baby from diseases. However, because the stimulation of the immune system by vaccination is relatively mild and there are certain inter-individual differences, the amount of antibodies in the body of some babies after vaccination is still relatively low and not enough to completely resist the invasion of pathogenic microorganisms, especially when the pathogenic microorganisms are prevalent and infectious, some vaccinated babies may still get sick, but the symptoms of these babies are relatively However, the symptoms of these babies are relatively mild, and serious diseases rarely occur.
